Tuning Vision-Language Models with Candidate Labels by Prompt Alignment

no code implementations10 Jul 2024 Zhifang Zhang, Beibei Li

In order to improve its robustness, we propose a simple yet effective framework that better leverages the prior knowledge of VLMs to guide the learning process with candidate labels.

Atrial Septal Defect Detection in Children Based on Ultrasound Video Using Multiple Instances Learning

no code implementations6 Jun 2023 Yiman Liu, Qiming Huang, Xiaoxiang Han, Tongtong Liang, Zhifang Zhang, Lijun Chen, Jinfeng Wang, Angelos Stefanidis, Jionglong Su, Jiangang Chen, Qingli Li, Yuqi Zhang

In addition, data from 30 children patients (15 positives and 15 negatives) are collected for clinician testing and compared to our model test results (these 30 samples do not participate in model training).

Rack-Aware Regenerating Codes with Fewer Helper Racks

no code implementations21 Jan 2021 Zhifang Zhang, Liyang Zhou

Previous work mostly focuses on minimizing the cross-rack repair bandwidth under the condition \(\bar{d}\geq \bar{k}\), where \(\bar{k}=\lfloor\frac{k}{u}\rfloor\).
